CC   -!- FUNCTION: Activation of pyruvate formate-lyase 1 under anaerobic
CC       conditions by generation of an organic free radical, using S-
CC       adenosylmethionine and reduced flavodoxin as cosubstrates to produce
CC       5'-deoxy-adenosine. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=glycyl-[formate C-acetyltransferase] + reduced [flavodoxin] +
CC         S-adenosyl-L-methionine = 5'-deoxyadenosine + glycin-2-yl radical-
CC         [formate C-acetyltransferase] + H(+) + L-methionine + semiquinone
CC         [flavodoxin]; Xref=Rhea:RHEA:19225, Rhea:RHEA-COMP:10622, Rhea:RHEA-

CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000250};
CC       Note=Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3
CC       cysteines and an exchangeable S-adenosyl-L-methionine. {ECO:0000250};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the organic radical-activating enzymes family.
CC       {ECO:0000305}.
